Checks and Adjustments
5. If available, use the drum alignment tool to measure the distance the
drum is out of alignment. Set the tool on the rails at the right end of
the drum. Turn the tool’s adjustment knob until the tool’s tip contacts
the drum surface. Zero-out the reading on the tool.
If you do not have the drum alignment tool, you will have to make
successive “best guess” adjustments and test prints to bring the drum
into alignment.
6. Back off the drum alignment tool’s adjust knob and slide the tool to
the left end of the drum. Turn the tool’s adjustment knob until the
tool’s tip contacts the drum surface. Read the displayed value. It will
show the difference in alignment from the first reading. The value
read should be no more than +/- 5 mils (.005 in.).
7. At either the left end or the right end of the drum, loosen the drum
bearing securing the drum to the printer frame. At the right end of the
drum you must remove the maintenance station and the maintenance
station drum cam. At the left end, you must remove the ink loader
and portions of the Y-axis drive.
8.
With one of the bearings loosened, push that end forward or
backward to bring the drum into alignment. With the drum
alignment tool, you can verify the alignment as you make the
adjustment.
9.
Once the alignment is correct, tighten the bearing, reassemble the
printer and make another test print.
10. Repeat the adjustment until it is correct.
